Justin Martyr

You are aware, then, that when the ark of the testimony was seized by the enemies of Ashdod, and a terrible and incurable malady had broken out among them, they resolved to place it on a cart to which they yoked cows that had recently calved, for the purpose of ascertaining by trial whether or not they had been plagued by God's power on account of the ark, and if God wished it to be taken back to the place from which it had been carried away. And when they had done this, the cows, led by no man, went not to the place whence the ark had been taken, but to the fields of a certain man whose name was Oshea, the same as his whose name was altered to Jesus (Joshua), as has been previously mentioned, who also led the people into the land and meted it out to them: and when the cows had come into these fields they remained there, showing to you thereby that they were guided by the name of power; just as formerly the people who survived of those that came out of Egypt, were guided into the land by him who had received the name Jesus (Joshua), who before was called Oshea.

And that the souls survive, I have shown to you from the fact that the soul of Samuel was called up by the witch, as Saul demanded. And it appears also, that all the souls of similar righteous men and prophets fell under the dominion of such powers, as is indeed to be inferred from the very facts in the case of that witch. Hence also God by His Son teaches us for whose sake these things seem to have been done, always to strive earnestly, and at death to pray that our souls may not fall into the hands of any such power.
